I have upgraded to Gnome3(version:3.2) in Debian Testing.
In Gnome-Shell(Gnome3) Session, Firefox shows misaligned pages, particularly the ones having more images,flash etc. also, jerky scrolling. it occurs in random websites. I managed to capture one image when I was posting a youtube video to a forum:http://upl0ad.org/images/iceweasel.png

Here is a Desktop screen capture video I recorded which will elucidate the issue faced. Please see the video(Zip format 4MB):http://www.mediafire.com/?liie7lj3bo6d4rw
I have tried disabling sync vblank settings and it doesn't help.
While in Gnome-fallback option, Firefox(Iceweasel) works fine.
Is this an issue with nvidia driver?
nvidia (debian)version: 290.10
gfx card: nvidia geforce 7300GT
distro: Debian wheezy/sid

It is a issue with nvidia driver verified. gnome-shell works fine with default driver which is auto installed in linux mint distro for eg.
I want to know, if this bug is fixed? if not, where do I report this issue

I installed, latest nvidia(beta) 295.09 in this Debian testing system upgrading from 290.10 . but, the poor slow performance/rendering issue is still persisting.

I have attached nvidia-bug-report.

I tried to verify that the problem is with mutter window manager and nvidia driver interaction.

steps to reproduce:

* login into Gnome Classic(fallback) 3.2
* run "mutter --replace" (I've installed mutter 3.2 already)
* try using browsers,image viewers all pages/images looks garbled,misaligned especially if You slowly scroll with mouse. if I try to press any key or launch any application meantime like for example gnome-screenshot tool, the page suddenly align correctly. same with image viewing tools also. I believe, after using for few hours, the image acceleration became slower.

However, with metacity window manager, there is no such issues. gnome-shell has libmutter0 as dependency.
helpful people at Debian forums suggested the image rendering issue may be related to Clutter Library as "eye of gnome/shotwell" like apps render images out of sync.
Here are the details of installed versions:

i have same problem but in openSUSE 12.1 with KDE 4.7.
before installing nvidia 290.10, openSUSE and its KDE worked very fine and smooth but after installing nvidia 290.10 driver, system performance decreased. Firefox scrolling became slow, pdf documents scrolling became slow, and when i start firefox system freezes for about 10 seconds and etc.
how can i solve the problem?

I think, a Video of what is Happening when I slowly Scroll using mousewheel(usb mouse) through Firefox(Iceweasel) web browser page will be helpful to Nvidia developers.
